So I pre-ordered Crysis 2 and now that I dl and can play, the MP doesn't work. It gave me 2 CD-keys, one is the Limited Edition Game Code and the other is LE Bundle. I used the Limited Edition one since that's the only format it would take when I clicked Multiplayer, but when I try to join a server, it says that a valid code is needed to play multiplayer. When the game first started, it said 2 were needed and I can just push Shift+Tab to view them, but it only gave me a chance to put in 1. Tried exiting and doing it again, but no go. Help please?
